New VO3052 and VO3053 Non-Zero-Crossing 1.5-kV/µs dV/dt Phototriac Optocouplers

Features:
• 1.5-kV/µs dV/dt
• Isolate low-voltage logic from AC voltages up to 380 V
• Choice of 5-mA (VO3053) or 10-mA (VO3052) maximum trigger current to latch output
• Rated with a 600-V blocking voltage and can provide isolation between DC and AC voltages on 120-V and 240-V AC lines, giving designers a 2X or better safety factor for control of off-line voltages up to 240 V
• Available in 6-pin DIP package
• Direct replacements for industry-standard 1.0-kV/µs dV/dt phototriacs
• Companion devices to Vishay’s zero-crossing VO3062 and VO3063 1.5-kV/µs dV/dt phototriacs

Benefits :
• 1.5-kV/µs dV/dt performance
• Low maximum trigger currents of 5 mA (VO3053) or 10 mA (VO3052) facilitate an easy interface with microcontrollers and digital logic
• 600-V blocking voltage between DC and AC voltages on 120-V and 240-V AC lines, giving designers a 2X or better safety factor for control of off-line voltages up to 240 V
• Optimized for noisy environments

Applications:
• Control of resistive, inductive, or capacitive loads, including motors, solenoids, high-current thyristors, and relays
• Typical applications include refrigerators, air conditioners (HVAC), dishwashers, vending machines, industrial controls, AC motor drives, switches, switching power supplies, and solenoid/valve controls

The Perspective: Vishay’s new 1.5-kV/µs dV/dt non-zero-crossing phototriac optocouplers, which provide off-line control of AC voltages up to 380 V, can be used as direct replacements for industry-standard 1.0-kV/µs dV/dt phototriacs.
